Vulnerabilities > CVE-2014-9625 - Classic Buffer Overflow vulnerability in Videolan VLC Media Player
Attack vector
LOCAL Attack complexity
LOW Privileges required
NONE Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
The GetUpdateFile function in misc/update.c in the Updater in VideoLAN VLC media player before 2.1.6 performs an incorrect cast operation from a 64-bit integer to a 32-bit integer, which allows remote attackers to conduct buffer overflow attacks and execute arbitrary code via a crafted update status file, aka an "integer truncation" vulnerability.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

Security issues fixed : - Fix various buffer overflows and null ptr dereferencing (boo#914268, CVE-2014-9625). Other fixes : - Enable SSE2 instruction set for x86_64 - Disable fluidsynth again: the crashes we had earlier are still not all fixed. They are less, but less common makes it more difficult to debug. On openSUSE 13.1 : - Update to version 2.1.5 : + Core: Fix compilation on OS/2. + Access: Stability improvements for the QTSound capture module. + Mac OS X audio output : - Fix channel ordering. - Increase the buffersize. + Decoders : - Fix DxVA2 decoding of samples needing more surfaces. - Improve MAD resistance to broken mp3 streams. - Fix PGS alignment in MKV. + Qt Interface: Don last seen 2020-06-05 modified 2015-02-06 plugin id 81199 published 2015-02-06 reporter This script is Copyright (C) 2015-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/81199 title openSUSE Security Update : vlc (openSUSE-SU-2015:0201-1)
